Back in May veteran reliever Guillermo Mota was suspended 100 games for his second positive performance enhancing drug test and today the right-hander rejoined the Giants’ active roster after serving his punishment.

MLB did not deny that Mota’s story was plausible, yet the punishment stood and he sat out 100 games without pay. Now the 39-year-old returns to a team that just lost Melky Cabrera to a 50-game suspension and will give the Giants some middle relief innings down the stretch.

I’m not defending Mota, but my impression is that MLB was so thoroughly hounded on drug issues that they have now gone to the other extreme. Can someone tell me when was the last system that produced 0% false positives? Are you telling me that out of all these guys caught not a single incident was an error (let’s leave Braun aside for a moment, that was an unsual procedural issue)? It’s like MLB will punish you no matter what, never admit that their process might have caught an innocent guy, for fear of looking lax on drugs.
